Streamlight Stylus Pro USB 350-Lumen Rechargeable Pen Light - Compact

In this review the Streamlight Stylus Pro USB pen light is evaluated as a small but capable tool for professionals who need reliable close-up illumination. The bottom line: it is best for technicians, medical staff, first responders, and law enforcement officers who want a slim, rechargeable light that delivers a focused bright beam without weighing down a pocket. The single biggest reason to buy is the combination of a credible 350-lumen white LED output with a fast USB recharge cycle, which makes it useful for extended shifts and everyday carry.

Key Features

• Ultra-slim design: The lightweight, pen-style body clips into a pocket or pouch for convenient everyday carry and easy access on the job.
• Bright white LED: A steady 350-lumen output provides a focused beam for inspecting tight or shadowed areas, improving visibility for detailed tasks.
• Rechargeable battery: The internal battery recharges via the included USB to micro-USB cable in about 2.5 hours, reducing ongoing battery costs and downtime.
• Long runtime options: Runtime measures roughly 1.5 hours on high and about 3.5 hours on low, giving flexibility between maximum brightness and extended use.
• Rugged construction: Built Streamlight tough with IPX4 water resistance and 1 m impact testing, so it tolerates drops and light splashes on job sites.
• Protected charging port: A sliding metal sleeve covers the USB port to help prevent damage and ingress while still allowing quick access to recharge.

Who It's For

The Stylus Pro is aimed at professionals who need a compact, dependable light for inspections and close work: field technicians tracing wiring above ceiling tiles, industrial inspectors examining confined welds, medical staff doing quick exams, and law enforcement officers who want a discreet, bright pocket light. Its slim form factor and clip make it easy to carry all shift long.

Those who frequently require very long continuous runtimes or multi-mode tactical features may want to look elsewhere; this pen light prioritizes compactness, brightness and rechargeability over multi-hour runtime on high or complex beam controls.
